COMBINED DOOR CHECK AND BUFFER.

To all whom it may concern:

Be it known that I, OARRIEG. GRIFFIN, of Manhattan, in the county ofRiley and State of Kansas, have invented a new and Improved CombinedDoor Holder and Buffer,

of which the following is a full, clear, and eX- act description Theobject of my invention is to provide a new and improved door-holder,which can also be used as a buffer or bumper.

The invention consists in the construction and arrangement of parts, aswill be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional view of my improved door holder,showing the manner in which it holds the door. Fig. 2 is a plan 'view ofthe same. Fig. 3 is a sectional view of the bumper on the wall, showingit so adjusted as not to hold the door. Fig. 4. is a face view of thesaid bumper, and Fig. 5shows a modification of the latch in the bumper.

On that surface of the door A that faces the wall when the door is opena button or bumper, B, is secured, which is provided in its top with aslot, 0, which coincides with a vertical slot, 0, in the door. In thesaid slot a latch-lever, D, is arranged, which is pivoted on the doorand is provided on the end projecting beyondthe button with a hook, D,and at the opposite end with a finger-plate, D.

A button or bumper, E, is secured on the wall in a positioncorresponding to that of the button 13, and is provided with a verticalslot, E, in which a tumbler, F, having one rounded or beveled edge, ispivoted at or near the middle of the bottom of the slit. The buttons orbumpers can have any desired shape, but are preferably madesemi-spherical, and are made of rubber, metal, wood, or of two orseveral of these materials combined.

In the modification shown in Fig. 5 a hookplate, H, is arranged on thebottoniof the slit E in the bumper, and above the said hookplate alatch, J, is pivoted.

The operation is as follows: If the door is to be held when open, thetumbler F is swung down so as to leave a clear space between itsPECIFICATION .orming part of Letters Patent No. 321,964, dated July 14,1835.

Application filed July 15. 1884.

(Modem inner end and the wall. When the door is opened, the hook D ofthe latch lever D strikes the beveled edge of the tumbler, slides up thesame, and then catches on the inner or butt end of the tumbler, as shownin Fig. 1, thus holding the door open.

To release or disengage the door, the fingerplate D is pressed down,andthereby the hook D of the latch is raised.

It the device is not to hold the door open, the tumbler is swung up andtoward the rear, as shown in Fig. 3, so that the hook D of thelatch-lever cannot catch on the tumbler. Inthis case the device acts asabumper or buffer onlv.

\Vhen the modified bumper in Fig. 5 is used, the latch Jinust be swungup if the hook D on the latch D is to catch and hold the door open. Whenit is desired that the latch shall not catch on the bumper and shall nothold the door open, the latch J must be swung down, as shown in dottedlines, so as to cause the hook D on the lever D to slide up the same andprevent it from catching.

Having thus described my invention, what I claim as new, and desire tosecure. by Let ters Patent, is

1. The combination, in a door check, with the pivoted hook, of a bumperprovided with a pivoted latch or tumbler for engaging said hook, saidtumbler being adapted to be turned in one direction to engage said hookand to allow said hook to pass when turned in the opposite direction,whereby, when attached to a door and wall, said door-check may be usedas an ordinary bumper or a positive means of holding the door open,substantially as set forth.

2. The combination, with a bumper having a slit, of a tumbler pivoted inthe slit at or near the middle of the bottom of the same, substantiallyas herein shown and described.

3. The combination, with a door having a vertical slot, of a slittedbumper secured on the door, and a latch arranged in the slot in the doorand the slit in the bumper, substantially as, herein shown anddescribed.
